The season is the long-awaited crossover between Murder House and Coven.

Nicks guest-stars in Coven as herself. Rabe plays Misty Day, who was largely influenced by the iconic singer. Farmiga and Sidibe play witches Zoe and Queenie. Conroy is Myrtle Snow, the eccentric head of the Witches' Council. The news comes days after Murphy revealed he invited all of the Coven witches back to return for the upcoming eighth season.

Jessica Lange will reprise her original American Horror Story role of the tragic and intrusive Constance Langdon. The character was last seen taking custody of her neighbors' satanic offspring, also playing a part in the new cycle. Cody Fern (American Crime Story: Versace) will take on the role of Michael Langdon, the evil baby from season one.

Sarah Paulson will reprise both her Coven and Murder House characters, and direct the episode in which her longtime friend and former co-star Lange would return (episode six).

The Apocalypse cast also includes Kathy Bates, Evan Peters, Adina Porter, Emma Roberts, Cheyenne Jackson, Billy Eichner, Leslie Grossman and Billie Lourd, while Joan Collins joins as one very high-profile addition. Paulson also made it clear that she would primarily be playing her role from Coven, New Orleans witch Cordelia Foxx, also appearing as Murder House (and, briefly, Hotel's) medium Billie Dean Howard. Roberts is also playing her Coven role, Madison Montgomery.
